This works similarly to the @2.6.5.1.1. VAT‍ option above, but has some extra features. Because the EU consists of nearly 30 countries, it will set all of them to charge tax (based on the TaxRegime.config file in the root of the web, which contains a list of all EU members). VAT will be added to all orders from an EU country. But if the country is not the home country of the site, a VAT number field will show. If a valid EU VAT number is entered here, the VAT will be zeroed as the customer would declare this purchase and pay VAT in their own country at the prevailing rate.
